IMPROVEMENT IN LAMPS.

Specification forming part of Letters lfatent No. 36,692, dated October14, 1862.

To @ZZ whom it may concern:

Be it known that we, SAMUEL ADLAM, J r., and J nRnMIAn R. FoGG, both ofPortland, in the county of Cumberland and State of Maine, have inventeda new and useful Improvement in Lamp-Burners Provided withDraft-Chimneys; and we do hereby declare that the following is a full,clear-,and exact description of the same, reference being had to theaccompanying drawings, making a part of this speci` iication, in which--Figure 1 is a vertical central section of our invention, taken in theline .r w, Fig. 2. Fig. 2 is a plan or top view of the Same.

`Similar' letters of reference indicate corresponding parts in the twofigures.

This invention relates to an improvement in the manner of attaching thecone or deflector to the burner, as hereinafter fully shown anddescribed, whereby the cone and draft-chim-V ney may be very readilyturned aside or olf from the burner, so as to expose the wick-tube, andthereby render the wick accessible for trimming and lighting.

To enable those skilled in the art to fully understand and-construct ourinvention, we will proceed todescribe it.

A represents a burner,`which may be constructed in any of the knownforms employed for burning coal-oil and other similar hydrocarhons witha draft-chimney. j

Bis the wick-tube, of the ordinary fiat kind, which is provided withserrated wheels C for raising and lowering the wick.

D is a dat rim or band,-.which is perforated withu holes a, extendingall around it, as shown in Fig. 1. This rim or band is of such adiameter that it may fit snugly on the top of the burner and admit ofthe. perforations a being a triiie above its upper edge, as shown inFig. l. The rim or band has a projection,

b, extending out from it horizontally, and to this projection aprojection, b', .on the iiange or base c of the cone or deflectorE isattached by apivot, d. rIhe cone or deiiector is allowed to turn or workfreely on this pivot, so that it may be adj usted on the burner A, or beshoved '0H' from it at any one side, as indicated in red outline in Fig.2.

The cone or detiector E is of the usual form, and when adjusted on theburner for use'has its slot e in line with the top of the wick-tube B,as will be seen by referring to both figures.

The top of the wick-tube B is a trifle below the plane or level of theupper edge of the burner and the base c of the cone oi deflector, sothat the latter may be shoved on and off the burner without interferingor coming in contact with theY wick-tube, (see Fig. 1,) and the base cof the burner is perforated with holes e', which extend all around thecone, as shown in Fig. 2.

F is a spring, constructed of a flat piece ot metal extending downthrough the burner and attached by solder or otherwise to the lower partof the wick-tube, as shown at g in Fig. 1. rlhe upper part of thisspring passes through the side of the burner, and is bent upward inabout a vertical position, and catches into a notch or recess, h, in theedge of the base c of the cone when the latter is adjusted on theburner, and retains it in proper position, the spring being held in thenotch or recess by its own elasticity.

Gr is the glass draft-chimney, which is se-a cured to the base c of thecone or deliector by means of a screw, i, and catches j j, as shown inFig. 2. The iialne is supplied at its base by air which passes throughthe perforations k of the burner and through the perforations c of therim or band D, while the sides of the flame are supplied with air whichpasses up through the perforations or holes e in the base c in the baseof the cone. (See arrows in Fig.` 1.)

ln order to shove the cone E and chimney G off from the burner for thepurpose of lightA ing or trimming the wick, the spring F is pressed outfrom the notch or recess hin the edge of the base c, in order to admitof the cone being turned on its pivot d, the spring adjusting itself inits notch when the cone Vis shoved back on the burner inprojperposition. By this arrangement it will be seen that the chimneydoes not require to be detached from the cone at any time for thepurpose of trimming and lighting the wick.

Having thus described our invention, what we claim as new, and desire tosecure by Let-` ters Patent, is-- j 1. So combining a chimney and lampthat the chimney may be removed from over the Wick of the lamp by ahorizontallateral movea glass chimney, to be moved horizontally and mentof the chimney, and Without detaehing laterally relatively to thelamp-cap, and so as the chimney from the lamp, for vthe purpose to belatched toor unlatched from the cap, set forth. l substantially asshown.
